Explanation of Photograph Captions

Plant Names
Scientific name
For European plants this is normally the name given in Flora Europaea. However research has advanced since the Flora was published and in some cases, especially the orchids, a later, but commonly recognised, name is given. For other areas, the latest name is used.
English name
Standard English names for many species are not available. In some cases a sensible made-up English name is used, in others a generic or local language name is used or the name is omitted altogether.
Family
The scientific name of the family with an English name in parentheses.
Photo Location
Place
The name of the place and region where the photograph was taken. It should be noted that in sparsely populated districts this name may cover a wide area.
Grid reference
The grid reference, where available, using the Universal Transverse Mercator (UTM) system. From 1999 onwards this was obtained from a Global Positioning Satellite (GPS) receiver and previously from a suitable map if readily available. The position given is generally rounded to the nearest 1km. In the UK the Ordnance Survey grid system is used instead and positions are rounded to the 100 metres.
Altitude
The approximate altitude relative to sea level in metres, where available. The accuracy is typically plus or minus 50 metres unless it has been possible to confirm the value using an accurate large scale map.
Date
The date on which the photograph was taken.
Photo Details
Magnification
Because of the wide variety of display devices, magnification is not given as an absolute value. Instead the relative magnification is stated assuming that the long side of the picture is 36mm. This enables the actual magnification to be calculated by measuring the actual size of the picture on a particular display. Standard pictures are displayed with the long side of 512 pixels.
